Can not ping from fresh Fedora Core 1 install


I have had a server running Red Hat 9 working fine. I have now done a fresh install of Fedora Core 1 though. After this my networking on that computer is not working. I have a standard 10/100 ethernet card and I set it to the correct IP address, the subnet address of 255.255.255.0 and the gateway address of the IP of our Smoothwall router/firewall.

The interface is active, although I can not ping anything. When I ping it says host unreachable. I also can not do any other network activity such as Apache/Samba/web browsing.

The Smoothwall box also has DHCP running so I tried changing the settings for the network to use the DHCP, when I did this I recieved a message that said can not recieve an IP address from the DHCP server.

I checked the network card and the connection light is on, and everytime it pings it blinks the activity light. I have tried changing cables out with no luck also.

I also turned the iptables firewall off and tried pinging the Fedora computer from another computer on the network with no luck.

Any suggestions?

Pinging problems

Thanks for your fast reply. My ifconfig output says:

eth0 Link encap: Ethernet HWaddr 00:60:08:B0:d9:F8
inet addr: 192.9.200.112 Bcast: 192.9.200.255 Mask 255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU: 1500 Metric: 1

RX bytes: 0 (0.0 b) Tx bytes: 0 (0.0 b)
Interrupt: 11 Base address: 0xc000

and then it shows the info about the loopback interface. The route -n command shows:

Destination Gateway Genmask Flags Metric Ref Use Iface
192.9.200.0 0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0 255.255.0.0 U 0 0 0 eth0
127.0.0.0 0 255.255.255.0 U 0 0 0 lo
0.0.0.0 192.9.200.70 255.255.255.0 UG 0 0 0 eth0


192.9.200.70 is the gateway/router. I have no clue where that 169.254.0.0 address came from.

Oops, The 169.254.0. is fine, I have that on my route -n with my wireless card and Linksys gateway/router.

I thought I would look through the BIOS and I noticed that the monitor on the -5VDC line read -66VDC. We then started checking it and there is a red light on the motherboard too. So I believe it may be a hardware problem after all. The interesting thing to note though is this server was up 148 days, started up on July 21st before I decided to go install Fedora. I will post back tomorrow with my results.
